Onycholysis is a common medical condition characterized by the painless detachment of the nail from the nail bed, usually starting at the tip and/or sides.[1] On the hands, it occurs particularly on the ring finger but can occur on any of the fingernails. It may also happen to toenails.

Onycholysis can occur in many conditions, including psoriasis.[2] In thyrotoxicosis, it is thought to be due to sympathetic overactivity.[3] It may also be seen in infections or trauma.[4]
